TC74HCT574AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HCT574AP, TC74HCT574AF Octal D-Type Flip-Flop with 3-State Output The TC74HCT574A is a high speed CMOS OCTAL FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Its inputs are compatible with TTL, NMOS, and CMOS output voltage levels. Its 8-bit D-type flip-flops is controlled by a clock input (CK) and an output enable input ( OE ). All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features • High speed: fmax = 62 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • Compatible with TTL outputs: VIL = 0.8 V (min) VIH = 2.0 V (max) • Output drive capability: 15 LSTTL loads • Symmetrical output impedance: |IOH| = IOL = 6 mA (min) • Balanced propagation delays: tpLH ∼− tpHL • Pin and function compatible with 74LS574 Pin Assignment TC74HCT574AP TC74HCT574AF Weight DIP20-P-300-2.54A SOP20-P-300-1.27A : 1.30 g (typ.) : 0.22 g (typ.)

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be applied until 300 mW.
